Cosmetic case having sealing function

Abstract

Provided is a cosmetic case having a sealing function which prevents a gap from being formed between a main body and a cover, thus preventing cosmetics from being contaminated during a process of distribution. In the cosmetic case, a suction member can be reliably attached to the main body by suction force so that a gap is prevented from being formed therebetween. Therefore, cosmetics contained in the main body can be prevented from being contaminated during a process of distribution, and the weight of cosmetics can be maintained. Furthermore, when the user presses a button member, a cover opens and, simultaneously, the suction force of the suction member is removed, thus allowing the user to easily open the cover and suction cover unit.

What is claimed is: 
     
       1. A cosmetic case having a sealing function, comprising:
 a main body defining a receiving space therein and having an opening formed above the receiving space, with a support surface provided on an inner circumferential surface of the receiving space, the support surface being oriented facing the opening; 
 a suction cover unit inserted into the receiving space, the suction cover unit comprising a suction member closing the opening in such a way that a perimeter of an inner surface of the suction member is attached to an upper surface of the support surface by suction force; and 
 a suction force removal unit comprising: a button member having a first side portion disposed to be exposed to an outside from an outer surface of a circumferential side surface of the main body, and a second side portion disposed in a space defined inside the circumferential side surface of the main body; and a suction force removal member disposed inside the circumferential side surface of the main body at a position facing the second side portion of the button member, the suction force removal member being moved upwards by a pushing force of the button member so that an upper end of the suction force removal member passes through the support surface and moves the suction member upwards. 
 
     
     
       2. The cosmetic case as set forth in  claim 1 , wherein
 the second side portion of the button member is disposed below the support surface and comprises an inclined part provided around an inner surface of the circumferential side surface of the main body, the inclined part having an inclined pressing surface inclined downwardly towards a central portion of the main body, and 
 the suction force removal member comprises: a guide protrusion having an upper end passing through the support surface; and a movement guide protruding from the guide protrusion towards the inclined pressing surface, 
 wherein when the inclined pressing surface is moved towards the central portion of the main body by the pushing force of the button member, the movement guide that comes into contact with the inclined pressing surface moves upwards along the inclined pressing surface, whereby the upper end of the guide protrusion pushes the suction member upwards. 
 
     
     
       3. The cosmetic case as set forth in  claim 1 , further comprising
 a cover covering the opening, 
 wherein an insert hole is formed in the second side portion of the button member, the insert hole being open towards an upper portion of the main body, and a locking hook is provided in the insert hole and oriented towards the inner surface of the circumferential side surface of the main body, 
 a first side portion of the cover is rotatably coupled to a portion of the main body, and a locking protrusion is provided on a second side portion of the cover, the locking protrusion being inserted into the insert hole through the upper portion of the main body and locked to the locking hook, and 
 when the locking hook is moved by the pushing force of the button member, the locking protrusion is released from the locking hook. 
 
     
     
       4. The cosmetic case as set forth in  claim 1 , wherein
 the main body has a double structure comprising a first main body and a second main body disposed in the first main body, and 
 the suction force removal unit is provided in space formed between a circumferential side surface of the first main body and a circumferential side surface of the second main body, and a guide unit is provided on an inner surface of the circumferential side surface of the first main body or an outer surface of the circumferential side surface of the second main body, the guide unit guiding movement of the button member or the suction force removal member. 
 
     
     
       5. The cosmetic case as set forth in  claim 4 , wherein an elastic protrusion is provided on the second side portion of the button member, the elastic protrusion extending along the inner surface of the circumferential side surface of the first main body,
 wherein when the button member is pushed towards the second main body, the button member is elastically biased by elastic force of the elastic protrusion in a reverse direction. 
 
     
     
       6. The cosmetic case as set forth in  claim 1 , wherein the suction cover unit further comprises a puff receiving member provided on an upper surface of the suction member. 
     
     
       7. The cosmetic case as set forth in  claim 1 , wherein a side portion of the suction cover unit is rotatably coupled to the main body. 
     
     
       8. The cosmetic case as set forth in  claim 1 , wherein the suction member is made of soft material having elasticity and capable of providing suction force and is configured such that a lower surface thereof is gradually curved upwards from a perimeter thereof to a central portion. 
     
     
       9. The cosmetic case as set forth in  claim 1 , further comprising
 a tray provided in the receiving space of the main body to receive contents therein, the tray being configured such that an upper end thereof is disposed below the support surface.
